4125
EdgeTech’s 4125 Side Scan Sonar System was designed with both the Search & Recovery (SAR) and shallow water survey communities in mind. The 4125 utilizes EdgeTech’s Full Spectrum CHIRP technology, which provides higher resolution imagery at ranges up to 50% greater than non CHIRP systems operating at the same frequency. This translates into more accurate results and faster surveys, thus cutting down on costs.
